Calculate the number of moles of sodium chloride in 500cm of 3m sodium chloride solution
The number of moles of sodium chloride in 500 cm3 of a 3M sodium chloride solution is 1.5 moles.
To calculate this, first convert 500 cm3 to liters (500 cm3 = 0.5 L). Then, multiply the volume (0.5 L) by the concentration (3M) to get the number of moles (1.5 moles).
To calculate the number of moles of sodium chloride in a solution, we first need to determine the amount of sodium chloride present.
Given:
Volume of solution = 500 cm³
Molarity of sodium chloride solution = 3 M
Step 1: Convert the volume to liters
Since the molarity of the solution is given in moles per liter (M), we need to convert the volume from cubic centimeters (cm³) to liters (L).
1 cm³ = 1 x 10⁻³ L
500 cm³ x (1 L / 1000 cm³) = 0.5 L
Step 2: Use the formula to calculate moles
The formula to calculate moles is:
moles = volume (in liters) x molarity
moles of sodium chloride = 0.5 L x 3 M = 1.5 moles
Therefore, there are 1.5 moles of sodium chloride in 500 cm³ of a 3 M sodium chloride solution.
To calculate the number of moles of sodium chloride in a solution, you need to know the concentration of the solution and its volume.
Given:
Volume of solution = 500 cm³
Concentration of sodium chloride solution = 3 mol/L
Step 1: Convert the volume from cm³ to L.
1 L = 1000 cm³
Therefore, 500 cm³ = 500/1000 = 0.5 L
Step 2: Calculate the number of moles of sodium chloride using the molarity formula.
Number of moles = concentration × volume
Number of moles = 3 mol/L × 0.5 L
Number of moles = 1.5 mol
Therefore, there are 1.5 moles of sodium chloride in 500 cm³ of 3M sodium chloride solution.
